The Spring and Fall Migration Timetable information was compiled using information from books and magazines, (see Bibliography), America Online's Birding forums, searches on the Google/DejaNews site and many hours at the local public libraries. Alot of time and energy has been put into this Timetable and therefore, I ask that the information not be taken from this site and displayed on another site. If anyone wants this information for another web site, please provide a link to http://www.birdnature.com/timetable.html. Thank you.
How the Timetable Works:
This timetable is only for the Eastern US states of Alabama, Arkansas, Connecticut, Delaware, District of Columbia, Florida, Georgia, Illinois, Indiana, Kentucky, Louisiana, Massachusetts, Maryland, Maine, Michigan, Mississippi, North Carolina, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee, Virginia, Vermont, West Virginia and Wisconsin.
Arrival Date is an approximation date of when the migrating bird can first be seen while the Departure Date is an approximation of the latest date the bird can be seen. Some departure dates are missing on the Timetables, because the migratory bird may be a "Summer Resident" or a "Winter Resident". A good field guide will help in determining resident birds and migratory birds that are resident throughout a period of time.
Even though most cities in a given state are not listed, when birds migrate there can be a radius of up to 100 miles or more. Keep an eye on local weather conditions which can influence the arrival and departure dates of birds. Keeping a personal record and checking your dates with other bird observers around your area is a better guide.
If you find an error or would like to contribute your list of migratory dates, please send mail to firstname.lastname@example.org and I will include your name/homepage as a contributor.
